I'm using Cakephp (v3.0). I have got a field "num_max_intents" that I want that only takes values greater than 0 and also I want that "date" field be greater than actual date.. My validationDefault() code is the next:
public function validationDefault(Validator $validator){
$validator->notEmpty('num_max_intents')
->notEmpty('package')
->notEmpty('date');
return $validator;
}
What's the simplest way to do this?
For a simple solution, use a range validator:
$validator->add(
'num_max_intents',
'valid',
['rule' => ['range', 0, PHP_INT_MAX]]
);
This validator requires both the lower and upper limit to be set, so you have to use some value here. You can find all validators in Cake\Validation\Validation.
You can use a closure as a custom validation rule. Just remember to return true if the rule validates and false if it fails. For example, to check the date field is greater than the current date:-
public function validationDefault(Validator $validator){
$validator
->add('date', 'valid', ['rule' => function ($value) {
return $value > date('Y-m-d');
}]);
return $validator;
}
To validate "date" field I'm using this code:
public function validationDefault(Validator $validator){
$validator->add('date',
'valid', [
'rule' => function ($value) {
return $value > date('Y-m-d'); },
'message' => 'Invalid date.'
]
)
->notEmpty('date');
return $validator;
}
But when I select a date less than actual date on my form, the validator doesn't run correctly and doesn't show the error message... What's wrong?
